` IMPROVEMENT' IN INSULTGR'EQLDEBS.

TO ALL WIIOM IT MAY COOERN:

Be it known that I, RICHARD CnLROw, of Mnmaroneck, .county of Westchester, State of NewYork, have invented a new and improved Insulator-Holdem und Ldo hereby declare that the following is n. full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference ,marked thereon.

Figure 1 is an end view of the insulator and block Figure 2 is a side elevation of the same.

Figure 3 is a longitudinal section of the sume.

Ais the holder. 11b are the clutches that hold the insulator, f is the ange on the holder. z'is the screw that is turned into the block. C is the metallic covering on the block. zi is the insulator. e is the lng on the insulator. g is the block to which the holder is fastened. z z' 72" are the lianges by which the bloei: is attached -to the building.

The nature of my invention consists in providing a neat and ei'eetive insulator-holder, that can he put on to metallic roofs without injury to the rooting by making holes in the sume, and preventing the metallic covering from expanding and contracting without tearing or breaking.

Construction.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The holder A is made of malleable iron, or any other suitable material, withits clutches b tiungef, and 'screw z', as shown in figs. y1, 2, and 3. The two clutches are left open at the top, so as te" let the lug e on the insulator d pass through them. Then we provide n. square block, g, of wood, or any othersuitable material.` The block g is then covered with tin or any other suitable material. The covering o is fitted on over the block, and soldered on so as to make it water-tight. The covering is left long enough to turn up ond form the flange 'it h lt. All of the several parts now being made ond put together, the insulator is now ready for use.

peratz'on. after being mede as above described, is teken on the metallic roof by the workman; the line of the lightning-rod or telegraph wire is determined, thc line is then spaced oi", and the blocks arethen soldered on to the metallic roof, or made fast in any known Way, without making holes in the roof.

The insulutor`holder,'

Advantages. I The advantage of my invention consists in providing avreliable insulator-holder, that can be .attached to any metallic roofing without making holes in the roof or roofing, and allowing the metallic rooting to contract and expand without any interference on the part of the insulator-holder.

Claims.

What I claim as my invention, und desire tn secure by Letters Patent, is The combination of the block g, metallic covering c, und the holder A, for the purposes setforth.
